Introduction: Breadboard-friendly Multimeter
Using breadboards I soon faced the problem of the multimeter probes too thick to be plugged in the breadboard holes for a stable and handless contact.
I had the idea to modify my multimeter in order it to be much easier to connect to the breadboard
Step 1: What You Need
the material needed for this project is
A multimeter: In my case a DT830B
(I choose a cheap one because I preferred not to endanger of destruction an expensive device)
Female dupont connector Jumper wire for standard 0.1" breakaway headers.
Maybe a little of hot glue
The Tools needed are a
maybe a drill and hot-glue gun
Step 2: Open the Multimeter
Unscrew the screws and open the multimeter case.
If you can't see any screw they are probably in the battery housing.
Step 3: Place the Header Outside the Case
make a hole in the plastic case.
I used the hot tip of the soldering iron to make the hole(use an old tip or replace the tip with a steel nail for this job, don't ruin a good soldering tip for this), otherwise you can use a drill or a dremel.
The hole can accomodate the wire plastic female header or just the wires if you prefer to glue the header outside the case.
In my case i decided to place the header in the hole and hold it in place with the melted plastic from the case.
If you prefer you can hot-glue the connector outside the case
Step 4: Solder the Wires
Cut the wires ad the desired length
Strip the wires and solder the wires at the contacts of the traditional probes.
being interesten mainly in voltage and resistence measurement and in any case in small current measurements I soldered all the white wires to the (V - Ohm - mA) contact.
Step 5: Close the Case, You Have Finished
The conversion is finished and your multimeter is now breadboard friendly.
